C037800100011 DETECTOR (GELI) C037800100012 SAMPLE These target stacks consisted of (1) three 25 microm C037800100013 thick aluminum foils, or (2) a 50 microm thick C037800100014 uranium foil sandwiched between two sets of three 25 C037800100015 microm thick aluminum foils, (3) a similar stack C037800100016 with a 75 microm thick thorium foil instead of the C037800100017 uranium, (4) a similar stack with 50 microm thick C037800100018 tantalum foil. The three uranium thicknesses used C037800100019 were 53 mg/cm2, 88 mg/cm2, and 147 mg/cm2. C037800100020 METHOD (CHSEP,ACTIV,GSPEC) After irradiation in the C037800100021 circulating beam of 28 GeV protons at the Brookhaven C037800100022 Alternating Gradient Synchrotron, a rectangular area C037800100023 from each of the target stacks was stamped out for C037800100024 chemical separations. The samples were assayed either C037800100025 on a calibrated 30 cm3 Ge(Li) X-ray detector or on a C037800100026 calibrated Ge(Li) X-ray detector, with the dimension C037800100027 of 5 mm x 100 mm2 and a thin Be window. For all C037800100028 samples of a given element, the assay was made with C037800100029 the same detector and under exactly the same C037800100030 conditions. C037800100031 ERR-ANALYS (ERR-T) The errors were combined in quadrature to give C037800100032 the proper weighting factors in the procedure. C037800100033 (ERR-S,0.2,1.3) Counting statistics. C037800100034 (ERR-1,3.,5.) Chemical yield determination. C037800100035 (ERR-2,0.7,3.4) Secondary corrections. C037800100036 (ERR-3,0.3,1.2) Recoil loss corrections. C037800100037 (ERR-4) Detector efficiency. C037800100038 CORRECTION The final results have been corrected for recoil C037800100039 losses and for secondary contributions both to the C037800100040 monitor reaction 27Al(p,3pn)24Na and to neutron- C037800100041 excess products as determined in this work.
